Effective On: Feb 27, 2020

Dear Valued Customer,

We are contacting you today to announce a New WiFi/Bluetooth Module for the TS-4900 (TS-4900 Board Revision Change from Rev D to Rev E). Technologic Systems strives to ensure the longevity of our products, while continually improving our products, so with the End of Life of the WiFi/Bluetooth module on the TS-4900 we are happy to announce an upgraded WiFi/Bluetooth solution including 802.11a/b/g/n/ac (2.4 GHz, 5 GHz) and Bluetooth 4.2 BR/EDR/LE(Class2). 

In order to support this change all customers will be transitioned to the new Revision E of the TS-4900.  All Revision E Boards will ship with an updated pre-loaded software image. Customers using WiFi will be required to update their software images to target the new module.  A new DDR3 RAM has also been qualified and will begin shipping with Revision E boards.

The affected products are: TS-4900, TS-TPC-8390-4900, TS-TPC-8950-4900 (and most custom variants)

When LS Research's planed replacement for the TS-4900's original WiFi module fell through, Technologic Systems purchased a number of extra modules and began the search for a replacement device that would bring feature improvements to the WiFi/Bluetooth solution on the TS-4900.  We are pleased to announce the next revision of the TS-4900 will include the Silex SX-SDMAC-2832S+ based on the Qualcom QCA9377-3.  This radio supports 802.11a/b/g/n/ac (2.4 GHz and 5 GHz operation) Wave 2 MU-MIMO and Bluetooth 4.2 BR/EDR/BLE “Smart Ready”.  The module carries FCC/IC/CE/MIC certifications, and is a similar size to the previous module, supporting minimal layout changes to minimize impact on any certifications obtained for TS-4900 based products.

Evaluation hardware for the new Revision E TS-4900 with the Silex module will be available to ship to customers in early January.  For evaluation purposes the initial Revision E units will all be built with WiFi and the i.MX6 Quad core CPU. TS-4900 production will begin to transition to the Rev E hardware as customers complete their evaluation testing and the available inventory of the Rev D modules runs out.  All TS-4900 product models will be transitioning to Rev E.  Please contact us as soon as possible if you require assistance with your transition plan.

In order to support this change, the TS-4900 shipping software will be upgraded to a Linux 4.9 Kernel with Debian Buster. The new shipping software will transition into full production status in advance of the Revision E hardware transition.  A separate announcement will be sent when this transition begins.

All customers not using the WiFi/Bluetooth features who's production processes install a complete kernel/application image can continue to use the same image they are using today.  The Revision E hardware maintains backwards compatibility for all other features and does not require an updated software image.

All customers using WiFi/Bluetooth features who's production image is based on the standard TS-4900 Debian or Yocto images with the Linux 4.1 or 4.9 kernels will be able to easy upgrade their shipping image by simply unpacking the new drivers into their current image, no complicated build processes required.

All customers with custom U-Boot or Linux Kernel's, or other TS-4900 images please consult the User Manual for instructions.  Feel free to contact us at for assistance with this transition.

For more information please review the TS-4900 User Manual.  This will be updated with more detailed information/software as it becomes available.:

In conjunction with the new revision of the hardware Technologic Systems is also transitioning the RAM to a new DDR3 RAM device from Alliance Memory in order to continue supporting a long life cycle on the TS-4900.  We have fully tested this change on all products over the full temperature range of the product and this change has no impact to functionality, software, or performance, we are timing the release of the new RAM to the Rev E release to allow for easier tracking of deployments.

Please contact us before Feb 27, 2020 (2 years ago) if you are anticipating any troubles in transitioning so that we can support your efforts and plan appropriately.

Technologic Systems appreciates your business. If you have further questions or concerns, please contact us by either replying to this email or filling out the contact us form at
